Motors | Automation | Energy | Transmission & Distribution | Coatings DC Motors www.weg.net DC Motors WEG DC motors are designed with state-of-the-art project technology, resulting in compact machines with excellent dynamic properties able to meet the requirements of a variety of applications in the automation and process control areas. Technical Characteristics WEG DC motor line comprises a power range up to 10,000 kW, with torques from 2 to 200,000 Nm, and is used in different industrial applications, such as the paper and plastic industries, among others. Projected for drive by means of thyristor converters, the DC motors can be manufactured with voltages from 110 to 1000 V and frame sizes (IEC) from 90 to 1800, or larger sizes upon consultation. Powers up to 10,000 kW Terminology D N F 160 . 190 S Code Regarding the Length of the ND-Endshield or Number of Tracks of the Commutator Frames 90 to 132 S - short endshield (one size) Frames 160 to 450 S - short endshield M - long endshield Frame 500 M - long endshield (one size) Frames 560 and larger A, B, C, D (code related to the number of tracks on the commutator) Length of the Lamination Core in mm IEC Frame Cooling Types F – Independent forced ventilation D – Ventilation forced by ducts S – Self-ventilated E – No ventilation X – Independent forced axial ventilation A – Ventilation by means of air-air heat exchanger W – Ventilation by means of air-water heat exchanger Compensation N – Non-compensated machines C – Compensated machines Specifies Being DC Machine 2 DC Motors www.weg.net Constructive Characteristics Frame Laminated in high-quality steel plates in rectangular, hexagonal or octagonal shape, allowing supply by static converters in high dynamic duties with fast torque and current variations. Rotor and Stator Winding They are wound with copper wire enamel-coated with class H varnish and with insulation and impregnation system class F or H. Endshields In cast iron or welded, they allow the coupling of WEG tacogenerators model 1R or TCW and other accessories, tacogenerators and encoders upon consultation. Commutators Made of copper and with the highest quality insulating materials, they allow a perfect contact with the brushes and ensure excellent commutation conditions. Brush Holder Manufactured with high technology, they have dimensions, tolerances and pressures suitable for each application, ensuring a long useful life of the mechanical system. Brushes Made of electrographite, natural graphite or specified according to load conditions, they ensure a long useful life. Bearings Ball bearings or roller bearings according to the size and application of the motor. Oil-lubricated sleeve bearings for specific applications.
